Eucalyptus globules belonging to the Myrtaceae family was explored for the synthesis of zinc oxide nanoparticles and for biological applications. The aqueous extract of the synthesized zinc nanoparticles (ZnNPs) was characterized using UV-visible spectrophotometer, FTIR, SEM and TEM. The aqueous broth was observed to be an efficient reducing agent, leading to the rapid formation of ZnNPs of varied shapes with sizes ranging between 52–70 nm. In addition, antifungal activity of the biosynthesized ZnNPs was evaluated against major phytopathogens of apple orchards. At 100 ppm of ZnNPs, the fungal growth inhibition rate was found to be 76.7% for Alternaria mali, followed by 65.4 and 55.2% inhibition rate for Botryosphaeria dothidea and Diplodia seriata, respectively. The microscopic observations of the treated fungal plates revealed that ZnNPs damages the topography of the fungal hyphal layers leading to a reduced contraction of hyphae. This considerable fungicidal property of ZnNPs against phytopathogenic fungi can have a tremendous impact on exploitation of ZnNPs for fungal pest management and ensure protection in fruit crops.

This study includes the photocatalytic degradation of Rhodamine B (Rh.B) employing a heterogeneous photocatalytic process by using ZnO nanoparticles that was prepared by green sol-gel process. The structural, morphological, and its optical properties of ZnO Photocatalyst was studied using different characterization techniques such as Xray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), The influencing factors studied were the amount of the catalyst, the concentration of dye and pH on photocatalytic degradation of Rhodamine B. The experiments were carried out by irradiating the aqueous solutions of dyes containing photocatalysts with Sunlight. The rate of decolorization was estimated from residual concentration spectrophotometrically. Similar experiments were carried out by varying pH (3-11), amount of catalyst (0.25-2.0 g/L) and initial concentration of dye (5-50 mg/L). The experimental results indicated that the maximum degradation (71%) of dyes was achieved using ZnO photocatalyst at pH 10 after 240 min.
